Tall Cinquefoil.Potentilla arguta.
Found among tall grasses in fields and meadows in June.
The stout leafy stalk grows between 2 and 3 feet high; it branches for the flowers, and is stout, woody-fibred, and hairy to the touch. The color is a pale yellow-green, with red-brown hairs.
The root, and lower, leaves are divided into 3 to 11 long, oval leaflets, and are set on long stems; the upper leaves are 3-divided, and set on short stems which clasp the stalk with a pair of wings; the margin is toothed, ribs and veins being prominent, and the surface is downy with hairs. Green in color.
The flower has 5 petals, that are round with a pointed base, of a fine texture, and creamy-white color; the stamens are many, thread-like, and bright yellow; the yellow pistils are gathered prominently in the center. The calyx is 5-parted, and green; close beneath it occur 5 narrow, spreading bracts that are shorter than the calyx-parts, and green. The flowers, on short leafy stems, are placed in groups of two or three, forming loose terminal clusters.
The long pointed bases, by which the petals are attached, permit the calyx to be seen, from above, as a green star at the bottom of the shallow creamy cup; the calyx is noticeably flat, and sticky.
